Set in a fictitious continent reminiscent of the 1930s, Valkyria Chronicles depicts Europa, divided and ruled by two super powers: the Empire and the Federation. The Empire has set its sights on invading the principality Gallia, which shares its borders with the two superpowers, in an attempt to secure an invaluable natural resource, Ragnite. Within this struggle a hero named Welkin, and his fellow soldiers of the Gallian Militia, ‘Squad 7’ are fighting back against the invasion and the Empire’s attempts to unify the continent under its power.

"Thousands of years ago six demon kings, known as the Revenants, ruled the world with an iron fist and bloody swords. Donning the bodies of mortal vassals, they could live in the realms of man forever. The great hero and warlock Harbinger was the only one who could stand up to their power. One by one he hunted the Revenants, taking their spirits and casting them into the Well of Souls. Alas, the Revenants survived. As a young man you will travel to meet your uncle in the town of Madrigal.
